Which method is NOT typically associated with DNA extraction?

The tooth extraction method is not typically associated with DNA extraction. In forensic contexts, DNA is predominantly extracted from biological samples such as blood, saliva, tissues, or hair, and the methods used in these extractions include the Chomczynski method, the Galstun method, and phenol-chloroform extraction.

The Chomczynski method uses a reagent known as TRIzol, which facilitates the lysis of cells and isolation of RNA and DNA. The Galstun method is tailored for extracting DNA primarily from tissues. Phenol-chloroform extraction involves using phenol and chloroform to separate proteins from nucleic acids, making it a widely recognized technique to obtain high-purity DNA.

In contrast, the term "tooth extraction method" does not refer to a recognized laboratory protocol for isolating DNA but rather implies a dental procedure. The nature of forensic DNA extraction is to utilize specific reagents and protocols on biological samples rather than focusing on physical removal of teeth to obtain genetic material.
